Thanks for all your help! I got the topfin tank and sponge filter based on what you told me. I also sort of stalked your posts with your aquarium (the pic thread of all the tanks with a TON of pages lol) just to get a better idea for how to make it work since I knew I wanted the same tank :)
Hey there! I've been looking at 'post pics of your betta home' post and see your alot. How well do you like the Topfin tank? I really like the look of the cubes and can't decide between the Topfin or the Tetra. I hope you don't mind me asking.
